Research Interests

  • Biomechanics and control of locomotion in vertebrates
  • Evolution of skeletons
  • Morphological plasticity

I am currently using the cane toad as a model organism with which to explore how the vertebrate body stabilizes itself upon impact.  Tools used to investigate this topic include: electromyography, high-speed video, and force plates.  I am also continuing to investigate benthic locomotion in stingrays and skates.  This is currently in collaboration with researchers at Fairfield University.  Please contact me if you are interested in student research.
